Abstract

The invention discloses a closed-loop-type liquid heavy metal mechanical pump performance testing device. The closed-loop-type liquid heavy metal mechanical pump performance testing device comprises a melting tank, an expansion box, a storage tank, a liquid collecting box, a mechanical pump, a main loop pipeline, a valve, a flow meter, a heavy metal pressure gauge, a liquid level meter, a flow guiding pipeline, a gas source, a vacuum pump, a heating thermal-insulation layer, an experience section and the like. The mechanical pump is a driving force source of the whole device and is a tested and researched object. The outlet flow of the pump is changed by adjusting the valve, flow data are obtained through the flow meter, inlet and outlet pressure head (lift) data of the mechanical pump are obtained through the pressure gauge and the two sets of data are combined so that a mechanical pump hydraulic characteristic curve can be drawn through a mature theoretical calculation formula and used for assessing and testing the hydraulic efficiency and the work performance of the mechanical pump. A branch circulation loop is specially designed so that gas in the pipeline can be completely exhausted, the main loop pipeline can be fully filled with liquid metal fluid media in the whole testing process, and the testing accuracy can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of performance testing of liquid heavy metal mechanical pumps, in particular to a performance testing device of a closed loop liquid heavy metal mechanical pump, which is used for the hydraulic performance testing of the closed loop liquid heavy metal mechanical pump and the research device for structural design of flow-through components. Background technique [0002] With the continuous development of China's economy, the demand for energy is increasing day by day, and the problem of energy shortage is becoming more and more serious. In order to deal with and solve the energy problem, nuclear fission energy, as an effective measure to alleviate the world energy crisis, has attracted people's attention. However, the development of fission energy will also bring nuclear waste to human beings. Once leaked, it will cause incalculable harm to the earth's environment. [0003] The Accelerator Driven Subcritical ...
